Our Services
Road Sawing
The road saw or floor saw as they are commonly known is the most efficient way of cutting large amounts of horizontal concrete slabs, asphalt, and curb and channels.
Our road saws have the ability to cut to depths of 650mm, depending on the depth the capacity to 500 lineal meters in an eight-hour day. Road saws are ideal for the cutting and removal of concrete drive ways, ground slabs and suspended slabs, however they require adequate space for operation.
Electric Road Sawing
The electric road saw or floor saw as they are commonly known, require 32amp power and can perform all the works of the diesel road saw, but without the harmful fumes.
These saws are ideal for the sawing of trenches inside existing buildings, as well as lift shaft and service duct penetrations.
Acclerated can also supply hand held electric saws, See high frequency sawing for hand held saw works in poorly ventilated areas.
Soft Cut / Early Entry Sawing / Expansion Joint Cutting
Accelerated has a number of early entry saws for expansion joint cutting. These saws provide a 4mm wide 30mm deep cut and can be used to cut expansion joints in slabs as soon as you are able to walk on the slab.
Getting on the slab early reduces the chance of cracks forming prior to expansion joints being cut in.
Soft Cut sawing is completed dry which means no slurry to be cleaned which can potentially stain the finished surface. We also can provide vacuums to extract dust as required.
Hand Sawing
The Hand Saw which is commonly referred to as a “Demo Saw” is the most used saw in our fleet. This saw has the capacity to cut 150mm deep and can be used to cut through horizontal concrete or asphalt, as well as vertical concrete or brickwork.
Hand Saws are mainly used to create door openings, and penetrations in vertical walls, as well as small penetration in slabs and tight access areas.
The Hand Saw is ideal for all penetrations down to 400mmX400mm in 150mm thick
surfaces. Any penetrations less than 400mm wide will require stitch coring. – See Core Drilling or Stitch Coring for small penetrations.
The biggest disadvantage of the Hand Saw is the 2stroke fumes they create, so should not be used in poorly ventilated areas – See High-Frequency Sawing for poorly ventilated areas.
Ring Sawing
The Ring Saw is the deepest cutting hand-held unit available in the current market.
This saw uses a series of rollers to spin a ring around a stationary blade, this allows the blade of the saw to not have a center point and allows it to achieve a cut depth of 275mm.
These saws cut the same surfaces as the Hand Saw and are put to use when horizontal slabs or vertical walls are too thick for the Hand Saw.
The draw back of the ring saw is the running cost, prior to using the saw, surfaces are required to be cut with the hand saw to its full depth, then that cut is to be widened with a “Pre-cut blade” used on the Hand saw, then the Ring saw can be used to complete the cut.
These saws create 2 stroke fumes and should not be used in poorly ventilated areas – See High Frequency Sawing for poorly ventilated areas.
High Frequency Hand Sawing and Ring Sawing
High-Frequency Hand Saws and Ring Saws can complete the same works as the Hand Saw and Ring saw, but without the harmful fumes.
The saws have the ability to run off 15amp and 20amp power, with 20amp power being preferred as the saws run at a slower speed on 15amp power.
Accelerated can also provide generators if the worksite can not supply suitable power - See hire equipment for more information.
Core Drilling – 16mm to 1000mm+ Core holes
Our Core Drills can be completed to achieve round holes from 16mm all the way up to 1m+ in diameter through depths of materials up and beyond 2m.
Generally, 18-40mm core drilling is completed for starter bars, dowel bars and chemical anchors when hammer drilling has failed due to the presence of steel. They are also completed when holes for studs have to be in exact locations for a pre-fabricated hold down plates, this is due to core drilling being very accurate.
40mm core holes and above are often used for services penetrations through a variety of materials, however there are endless reasons as to why core holes need to be completed.
Our operators have the ability to complete core holes on flat surfaces, walls, and inverted into the soffit of concrete slabs. We can do them on virtually any angle to any depth depending on the diameter of the core hole.
All our operators carry 2 core drills, a small drill for 16mm-125mm core holes, and a larger drill for 125-250mm core holes. We also carry a range of bits from 18mm to 250mm
diameter cores, anything larger or small needs to be requested prior to our arrival on site.
Stitch Coring
Stitch sawing involves the coring of a series of core holes in a line to achieve a cut. This is often done through footings or piles where there is not enough room for a large saw to cut through or for penetrations less than 350mmX350mm that the hand saw and ring saw are unable to cut.
Stitch coring can be completed on materials beyond 2m thick, and if wire sawing is not an option it is the best method to cut through very thick materials.
Coring (to avoid overcuts)
When road saws and hand saws are used to cut through a structural slab it is often a requirement that there be no cuts made into the material that is to remain. In these scenarios, core holes in the corners of cuts leading to an edge are completed to ensure that the slab is cut right through prior to removing them.
Wall Sawing
Our wall saw is the pride of our fleet the Tyrolit Hydrostress WSE1621 has the ability to cut 710mm deep-running a 1600mm blade. These saws can cut perfectly straight as they run along a track fixed to the wall which allows for inverted cuts on angles if required.
These saws are remote controlled and are one of the safest ways to cut vertical concrete walls and upstands.
Wire Sawing
Our Tyrolit Hydrostress WCU17P is the latest wire saw on offer from Tyrolit and its limitations when cutting concrete are next to none.
The process of wire sawing involves using a series of pullies to direct a diamond wire around the section of concrete, stone, or steel that is to be cut, the wire is then joined to create a loop and pulled tight. It cuts the material by spinning around the material via the pullies, and gradually pulls tighter as it eats through the material.
This can be done around massed concrete footings, 700mm + thick walls, columns, or around plantroom plinths to cut them off flush. The possibilities with wire sawing are endless.
Cut and Removal works
Accelerated Concrete Sawing offers a cut and removal service for:
Suspended slab penetrations
Lift core extension
Door openings in tilt panels
Large commercial driveway removal
We can provide excavators, skid steers, crainange, back propping, and removal and disposal of concrete as required.
All works are accompanied by SWMS and demolition methodologies signed off with our Unlimited Demolition License.
Scanning of Concrete Slabs
Scanning of concrete slabs prior to cutting or coring is essential to ensure the strength of the structure is not lost by cutting or damaging structural elements in the concrete. It is also the best way to locate potential services or assets that may be located in the concrete.
We can scan slabs up to 400mm thick and provide 3D images as requested.
Floor Grinding / Floor Preparation
Accelerated has a number of floor grinders available for wet and dry hire. We have 280 and 600mm cutting head grinders used for floor preparation to remove waste build-up during construction, slurry or concrete, or to remove tile glue in renovations or waterproofing.
